' In the actual trol and the hand throttle control, the parts are beassumed that the throttle valve is closed, then-it"the hand throttlelever isactuated for rotating the hand throttle-rod 20, then acuate theeyelet 46 for against the collar 30 for pushing the rod 28longitudinally toward the'right side of the ear for actuating the lever'25and thus opening the throttle causing it to engage The rod or wire44,the rod foot actuated rod 82 move freely with the rod 28- and donotinterfere with'the hand control.

If it is desired to then close the throttle, the hand throttle lever,not shown, is moved in the opposite direction from that of its firstmovement, thus reversally rotating the hand throttle 20 for returningthe rod 28 valve toward" their original positions. g

Assuming that the throttle valve is closed and that it is desired, toactuate it toward opening position by means of the foot feed control,the operator presseson the head 32 with his foot, thus moving the rod 32forwardly in the car, and rotating the upright rod 39, whereupon therod44 pulls the collar 30 and the rod 28 toward throttle openmg position.

In actual practice, is mounted adjacent gated sector and is with sometension. when the foot feed opening the throttle, the hand rod 20, andthe hand lever and sector, not shown, and this" holding stretches andtensions the spring 45,so that when the foot pressure on the head 33 visreli'eved, the move -the rod 44 for opera-t1 2'8 toward throttleclosingposithe hand throttle lever to a notched or'corruheld against thesector On account of this fact, control is actuated for the eyelet 46 isheld by mg the rod tron. This is a'very simple and effective mechanism"for accomplishing the purpose,a-nd it is to be noted'that the footcontrol nism is mounted on the left side of the en'- gine. Usually themechanism is mounted on the other side of the engine, although notmecha- 7 always.

1 'Many foot accelerators are of the type which include a spring forimposing ten sion on the parts for constraining them toward throttleclosing position:

a disadvantage in that when the hand throttle -control mechanism isoperated for opening the throttle, the tension on such'a spring isincreased and in use of the foot feed 0on so constructed andarranged'that if it 39 and the control mechanism, including thevehicles,

It will be noted that with my foot feed" control attaclnnent hereindescribed, the construction and arrangement of the parts are such thatthe actuation of. the throttle towardopenposition by the hand throttlemechanism does not in any way inereasethe tension on the spring, noristhere any tension on thespring tending to close the throttle. There istherefore no danger of the hand throttle mechanismbeing accidentallymoved toward throttle closing position.- ,ThisI believeto be a novelfeature ofstruc-- ture 1n devices of this-kind Changes may be made inthe details of the structure and arrangement of the parts of my improveddevice without departing from the real spirit and pur or use ofmechanical equivalents, which may o lncluded wl-thintheir scopei;
